In this patch we also make sure to pass the interlacing mode provided by userspace from the output to the capture side of the device so that the information is given back to userspace. This way it can handle it and potentially deinterlace afterward. Signed-off-by: Thibault Saunier --- Changes in v6: - Pass user output field value to the capture as the device is not doing any deinterlacing and thus decoded content will still be interlaced on the output. Changes in v5: - Just adapt the field and never error out. Changes in v4: None Changes in v3: - Do not check values in the g_fmt functions as Andrzej explained in previous review Changes in v2: - Fix a silly build error that slipped in while rebasing the patches drivers/media/platform/s5p-mfc/s5p_mfc_common.h | 2 ++ drivers/media/platform/s5p-mfc/s5p_mfc_dec.c | 6 +++++- 2 files changed, 7 insertions(+), 1 deletion(-) diff --git a/drivers/media/platform/s5p-mfc/s5p_mfc_common.h b/drivers/media/platform/s5p-mfc/s5p_mfc_common.h index ab23236aa942..3816a37de4bc 100644 --- a/drivers/media/platform/s5p-mfc/s5p_mfc_common.h +++ b/drivers/media/platform/s5p-mfc/s5p_mfc_common.h @@ -652,6 +652,8 @@ struct s5p_mfc_ctx { size_t me_buffer_size; size_t tmv_buffer_size; + enum v4l2_field field; + enum v4l2_mpeg_mfc51_video_force_frame_type force_frame_type; struct list_head ref_queue; diff --git a/drivers/media/platform/s5p-mfc/s5p_mfc_dec.c b/drivers/media/platform/s5p-mfc/s5p_mfc_dec.c index 367ef8e8dbf0..6e5ca86fb331 100644 --- a/drivers/media/platform/s5p-mfc/s5p_mfc_dec.c +++ b/drivers/media/platform/s5p-mfc/s5p_mfc_dec.c @@ -345,7 +345,7 @@ static int vidioc_g_fmt(struct file *file, void *priv, struct v4l2_format *f) rectangle. */ pix_mp->width = ctx->buf_width; pix_mp->height = ctx->buf_height; - pix_mp->field = V4L2_FIELD_NONE; + pix_mp->field = ctx->field; pix_mp->num_planes = 2; /* Set pixelformat to the format in which MFC outputs the decoded frame */ @@ -380,6 +380,9 @@ static int vidioc_try_fmt(struct file *file, void *priv, struct v4l2_format *f) struct s5p_mfc_dev *dev = video_drvdata(file); struct s5p_mfc_fmt *fmt; + if (f->fmt.pix.field == V4L2_FIELD_ANY) + f->fmt.pix.field = V4L2_FIELD_NONE; + mfc_debug(2, "Type is %d\n", f->type); if (f->type == V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE) { fmt = find_format(f, MFC_FMT_DEC); @@ -436,6 +439,7 @@ static int vidioc_s_fmt(struct file *file, void *priv, struct v4l2_format *f) goto out; } else if (f->type == V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE) { /* src_fmt is validated by call to vidioc_try_fmt */ + ctx->field = f->fmt.pix.field; ctx->src_fmt = find_format(f, MFC_FMT_DEC); ctx->codec_mode = ctx->src_fmt->codec_mode; mfc_debug(2, "The codec number is: %d\n", ctx->codec_mode); -- 2.11.1
